We know that 49% of accountants taking the CPA exam fail the first time. This means that 51% pass on the first attempt.

We can find the expected number of candidates who will pass by multiplying the total number of candidates (1000) by the percentage who pass (51% or 0.51):

1000 x 0.51 = 510

Therefore, the expected number of accountants who will pass on the first attempt is 510.
